So I got my Squier Affinity Strat, surf green.

The finish looks pretty boring, only with a bright light can it look nicer. How do i better the finish? Going for the actual Fender surf green, and not the budget squier paint.

Is the finish going dull or do you just not like the colour?

I think your only option is a refinish.  Not a cheap option and probably not worth the money plus it'll kill resale value.

You could try sanding down the first few coats of lacquer and shooting a couple of coats of amber tint. That would make it look a little different.

But as CorduroyEW said , for an affinity strat you spending more than the guitars really worth.

black pickguard might make the colour pop more if you have a light one on it now. 
but you can't change the colour unless you change the colour.

As Well-Hung suggests, drawing attention away from the finish might work. Fancier pickguards can be found at WDMusic, Greasy Groove and other websites for @$35+.* They, along with sites like Q-Parts, would also stock different knobs and switch covers.

So you could easily trick out your guitar for less than $100 in such a way that would make people miss the "plain-Jane" Green is not quite as nice as the ones on higher priced Fenders.

Plus, all of those mods would be 100% reversible.


* they don't stock pockguards for all Squier models, but most of those sites can and will make a custom guard if you send them a template.

Log off and play yer guitar!

Strap on, tune up, rock out!

Another vote for a fancy pickguard if you are looking for less-boring. If you are into DIY, this offers all sorts of interesting possibilities, for example, clear acrylic decorated from the back. I use plain black, but I have made fancy fretboards Valco-style lap steels like that.
